Method and apparatus for controlling network access of machine terminal

Abstract

Embodiments of the present invention disclose a method, an apparatus, and a system for controlling network access of a machine terminal. In the embodiments of the present invention, an authorized period and/or a forbidden period of a time-controlled subscription is generated according to information such as network service load historical data of a network and application information of the time-controlled subscription. Network access of the machine terminal is controlled according to the authorized period and/or the forbidden period. Because the network access time of the machine terminal can be controlled flexibly, the communication of the machine terminal can be controlled flexibly, and impacts of machine terminal communication on ordinary terminal communication can be reduced.

       6. The method according to  claim 1 , wherein the controlling access of the first machine terminal comprises:
 determining whether to allow the access of the first machine terminal according to the authorized period and the forbidden period of the first time-controlled subscription. 
 
     
     
       7. The method according to  claim 6 , further comprising allowing the access of the first machine terminal or denying the access of the first machine terminal. 
     
     
       8. The method according to  claim 6 , further comprising:
 allowing the access of the first machine terminal; and 
 adding a label for a current access so that predetermined processing is performed according to the label. 
 
     
     
       9. The method according to  claim 1 , further comprising:
 determining whether the first machine terminal is a machine terminal of the first time-controlled subscription; and 
 executing the control of the access of the first machine terminal according to the authorized period and the forbidden period of the first time-controlled subscription if the first machine terminal is of the first time-controlled subscription. 
 
     
     
       10. A method for network access of a machine terminal, the method comprising:
 performing time synchronization with a network-side system, the time synchronization being performed using a global positioning system (GPS); 
 obtaining, by the machine terminal, a first authorized period and forbidden period of a time-controlled subscription, and a local authorized period and forbidden period, wherein the first authorized period and forbidden period of the time-controlled subscription are generated by a network-side device according to requirement information, wherein the requirement information comprises application information of the time-controlled subscription and network service load historical data; and the local authorized period and forbidden period is generated by the network-side device according to the first authorized period and forbidden period of the time-controlled subscription and a predetermined local policy;
